.RDP files won't open (remote desktop) after Win10 Anniversary Update

Question

After the Windows 10 Anniversary Update was installed on my Windows 10 Pro, .RDP files won't open. Remote Desktop still works if you open it manually and enter in the server info. But my saved .RDP files won't open. Also, right clicking on them and selecting
edit also does not work. Nothing happens. I even opened Remote Desktop connection, entered in the server info manually and clicked Save As. That shortcut also won't work. Any ideas on what's wrong? Thanks.

I'm still investigating the issue to determine if it's a feature removed from Windows Pro (like many others - thanks MS!) or another issue. FYI, you can edit the .rdp file with notepad to view your connection info.

No, I am having the same problem after an Aniversary Update but on a VM with a fresh install of an Aniversary ISO, the above problem does not occur. So it must be the update that broke something.

Yeah, indeed great find for a beer, but certanly not a solution, because many of us here need 100% scale factor to work. Let's hope MS will correct this ASAP, because RDP is hi-priority, especially nowadays.

Thanks for this! I had the same probleme and don't want to switch between custom and 100% display settings. But your way is a good workaround to stay in custom settings and get the .rdp-files to work. I hope Microsoft will fix this bug since the Anniversary
Update soon!

Trying to repro this -- is this happening on latest Windows 10 14393.103? Can you provide some repro steps? It's not clear what the problem is. I set my scale factor >100% on the host machine and can use RDP files with no problem.

This is a Microsoft Windows confirmed bug. It is solely caused by custom display font scaling. See the message above by rafid123 (August 16, 2016 1:01)for instructions on how to resolve this issue very easily.

Currently I have several systems with this issue. I ran all the updates on several systems to recreate this issue. not all the fully upgraded system encountered this issue. the ones that did all had the Display setting set to 100%.
This fix did not resole the issue. I even set the display to the 125% setting signed out and then set it back without effect. I did confirm this happened immediately after the anniversary update. I usually reserve recreating user profiles
as a second to last resort. so I followed the file replacement option without success. currently working to undo that and recreate profile.

If you are experiencing this issue, you should be able to work around it by removing the custom scale factors you have set (a custom scale factor applies across all monitors).

1. Hit the Windows key and then type "display".

2. Tap on the "display settings" link that is found.

You should see the following text in red: "A custom scale factor is set".

3. Click on the text underneath which states "Turn off custom scaling and sign out".

4. Sign back in.

If the above does not resolve the problem, they can also manually connect to work by following these instructions:

First, get your settings:

Open your .rdp file in notepad.

Copy the information after these headings:

full address:s:

username:s:

For example, if you see:

full address:s: server.com

username:s: user

Then your computer name is: server.com

and your user name is: user

You will need to already know your login password.

Then:

1. Hit the Windows key and then type "Remote Desktop Connection" and click on it.
2. Click on Show options in Remote Desktop Connection
3. Copy and Paste the settings for computer and user name into the appropriate fields and click connect.

Obviously this is slower than just double-clicking the RDP file, but a lot faster than copying/pasting settings from notepad, at least if you're setting any custom settings like size, resource sharing, etc.
